1. A system for decreasing the risk of erroneously handling of a tool in a machine operation, wherein the tool includes a first tool part and a second tool part, wherein the system comprising:
a reader device for reading machine readable codes arranged at the first and second tool parts during usage of the tool parts in a machine operation by a machine;
an electronic device configured to be connected to the reader device, the electronic device having a processing circuitry configured to cause the system to:
receive, at the electronic device, desired operation data indicative of the first and second tool parts to be used during the machine operation by the machine, wherein the desired operation data includes data indicative of a desired location of the first tool part in relation to the second tool part during usage of the tool parts in the machine operation;
detect, by the reader device, a first identification marker at the first tool part and a second identification marker at the second tool part;
read, by the reader device, the machine readable codes of the first and second identification marker markers;
identify the first and second tool parts by information in the read machine readable codes of the first and second identification markers;
determine if the identified first and second tool part parts associated with the read machine readable codes correspond to the first and second tool part parts according to the desired operation data;
determine, before and/or during usage of the first and second tool parts in the machine operation, a location of the identified first tool part and a location of the identified second tool part in relation to each other or in relation to other tool parts;
determine if the first tool part and the second tool part are arranged at locations according to the desired operation data;
issue a stop signal indicative of a stop command to the machine, upon a determination that the identified first and second tool parts associated with the read machine readable codes do not correspond to the desired operation data; or at least one of the first and second tool parts can no longer be identified by the machine readable codes; and
stop the machine operation based on the issued stop signal.
